Patent No. 789,116, dated May 2, 1905.

Application tiled April 8, 1904. Serial No. 202,154.

To {IJ/Z wh/077@ it NM1/U concern:

Be it known that I, WILLIAM BRoUGH, a citizen of the United States, anda resident of Baltimore, in the State of Maryland, have made certain newand useful Improvementsin Seed- B/Ieasuring Machines, of which thefollowingI is a speciiication.

The object of my invention is to provide an improved automatic machinefor measuring seeds or granular material and delivering the same to bagsor other receptacles. I have aimed at compactness, durability,simplicity, and economy of construction and also at convenience ofadjustment of certain parts for varying the quantity or charge of seedsor other material measured and delivered at a given time.

The details of construction, arrangement, -and operation are ashereinafter described, 2O reference being had to the accompanyingdrawings, in whichM Figure l is a perspective View of the entiremachine. Fig. 2 is a perspective view of the different portions of thecharge-carrier separated or disassociated from each other. Fig. 3 is aplan view of the machine. Fig. 4 is in part a side view and in part avertical longitudinal section of the machine. Fig. 5 is a verticalsection mainly on the line 5 5 of 30 Fig. 1. Fig. 6 is a verticalsection on the line 6 6 of Fig. 4. Figs. 7 and 8 are detail views ofparts which will be hereinafter referred to. Fig. 9 is a viewillustrating the construction of the charge -carrier and its swingingsupport. Fig. 10 is a perspective view of the carrier, together with aportion of the wiper or rotating lever by which it is moved in onedirection.

I will first indicate the main portions of the machine as seen in Fig.l. The seed or other material which is to be measured and delivered intobags or other receptacles is first deposited in the hopper A andconveyed thence by the vertical tube B into a receiving-hopper O./Vithin the latter is arranged to revolve a device D, consisting of aseries of radial buckets or scoops which take up the seeds or othermaterial and deposit the same 1n the carrier E. The latter forms anattachment of a right-angular lever-arm F, which is acted upon by arotating wiper Gr, that forms an attachment of the shaft H, to which thebuckets are attached. The wiper swings the carrier back to normalposition after discharge into the tapered hopper I, and the carrier isheld during a part of the revolution of said shaft by a device J, whichforms practically a slotted hub on the wiper G. The carrier is thrownoutward or in direction for discharge by a spring K. The shaft H isdriven by worin-gear L, operated by a horizontal driving-shaft M, towhich aband-pulley N is shown aiiiXed.

The shaft H operates an agitatingdevice, which is located within thevertical hoppertube B, the said device being connected with the shaft bymeans of a threaded rod O.

I will now describe the details of construction, arrangement, andoperation. All the aforementioned parts are suitably arranged 7C on andattached to a horizontal base or platform P. TheA receiving-hopper O(see Figs.

3 and A) is formed with sloping sides converging to a horizontal middleportion 1 and which is provided interiorly with a shallow groove whereinthe outer ends of the buckets or scoops D work. As indicated in Fig. 5,these arms are curved slightly longitudinally and their outer portionsare formed of pockets or scoops proper, the end portions being 30 aspring-plate 2, whose free end works in contact with the bottom of thegroove in the receiving-hopper, as will be readily understood. The innerportions of the buckets are open on one side-to wit, the side adjacentto the car- 85 rier E. The arms are also curvedlengthwise,

so that they have practically a spiral shape, and the rear sides areextended or closed, as shown in Fig. 5, while cut away on the front,

so that the material taken up by them is discharged at the front andinto the carrier O as the buckets successively rise to the requiredheght. The double-headed arrows in Fig. 5 indicate the buckets fromwhich discharge is going on.

The carrier E, as shown in Figs. l and 2,

is constructed of two parts 3 and 4, which are adjustably connected, sothat the carrier may be enlarged and reduced in size according to thequantity of seed or other material required to be discharged at a giventime. The two parts 3 and 4 are adjustable laterally, the part 4 beingprovided with a screw and the part 3 with a slot adapted to receive thesame and a wing-nut 5 being applied to the screw for securing the partsin any required adjustment. The carrier forms afixed attachment of aright-angular arm or lever F, (see Figs. 9 and 10,) which is pivoted at6 on the platform or base P and provided with a toe or lateral extension7, against which the spring K acts, as shown in Figs. 1 and 9. In Fig. 9I show an adjustable screw 8, arranged in a bracket 9 and serving toregulate the throw of the carrier-lever F. It will be noted that thesaid lever is hinged in such manner that the carrie-r E swings in adirection slightly inclined to the face of the buckets or bucket-wheelD. (See especially Fig. 3.) As shown best in Fig. 4, the hub or innerportion of the buckets D is recessed at 11 concentrically with the shaftH and serves to accommodate the carrier E when returned to its normalposition.` In other words, the carrier is thus adapted to be placed insuch relation to the face of the bucketsl) that their contents willdischarge into it with greater certainty ,and no'seed or other materialcan find its way or wedge between the carrier and the hub of thebuckets.

The throw of the carrier E is indicated by Y dotted lines, in Fig. 3,and since its fulcrum 6 is at a point intermediate of the driven shaft Hand the discharge-spout I the receiver is inclined downward sufficientlyto cause discharge of its contents when it reaches the positionindicatedby dotted lines. As before intimated, this throw is occasioned by theaction of the spring K. The means forreadjusting the carrier orreturning it to normal position (indicated in Fig. 1 and by full linesin Figs. 3 and' 6) is the wiper or two-armed lever G, which forms afixed attachment of the shaft H and is provided at its ends with lateralpins 12, that act successively upon an angular lever-arm 13, (see Fig.10,) forming a rigid attachment of the carrier-lever F. In other words,at each revolution of the shaft H the wiper Gr acts twice upon thelever-arm 13 and each time swings the carrier E back to its normalposition against the opposing tension of the spring K. When the pins 12of the wiper G pass out of Contact with the bent lever-arm 13, theholder J comes into action. This, as shown in several figures, ispractically a slotted hub forming an attachment of the wiper G and theshaft H. As shown in Fig. 9, it consists of two semicircular orarc-shaped portions 14, which are arranged opposite each other andprovided with opposite notches or slots. As illustrated in Fig. 1, thelower pin 12 of the wiper-lever G is just leaving the free end of theangular lever-arm 13, and a pin 15, projecting from the head of-thecarrier-lever F, is just entering the holder J, so that the latter willretain the carrier in the normal position until the said pin 15 reachesthe opposite slot, when it will be released and the spring K will throwthe carrier over to the dotted position indicated in Fig. 3. After amomentary pause the wiper G again comes in contact with the lever-arm 13and forces the carrier E back toits normal position. Thus the pins 12 ofthe wiper G act alternately on the curved portion of the holder J, andthe pin A15 of ,the carrier-lever F enters and leaves the retainer ateach half-revolution of the wiper.

While the downward inclination of the carrier E at the end of its throwordinarily suffices to cause discharge of its contents, it is to benoted that this operation is aided by the sudden impact or contact ofthelever arm or toe 7, forming an attachment of the lever F, with thestop-screw 8. shock due to impact aids in effecting discharge of thecontents of the carrier if the same tends from any cause to becomewedged or otherwise stick therein.

Within the hopper-discharge tube B (see Fig. 4) is arranged areciprocating agitator 16, which consists of a sinuous wire or rod whoseshorter arm is secured by a clampscrew 17 to a slide-bar 18, arrangedbetween guides 19, forming an exterior attachment of the said tube B.This slide is reciprocated by a screw-threaded rod 20, which is attachedto a crank l21, forming an attachment of the driven shaft 8. The limitsof the throw or reciprocating movement of the agitator 16 are determinedby the adjustment of nuts 21 on the rod 20, these being arranged onopposite sides of a pin 22, forming an `attachment of the slide 18. Thereceiving-hopper A (see Fig. 1) is supported by rigid bars 23, forming apermanent attachment of the receivinghopper C. The discharge-tube B maybe adjusted vertically, as required to regulate discharge of itscontents into the hopper C, by means of a band 24, (see Fig'. 4,) whichis, in etfect, a screw-clamp permanently attached to the hopper at 25,as shown.

It is sometimes desirable to reduce the number of throws or oscillationsof the seed-carrier E--as, for instance, when a large quantity of seedis to be bagged at each throw. In

In other words, the

IOO

such case one of the slots of the retainer J l may be closed by a device26, (see Figs. 7 and 8,) which is a curved metal piece having anenlarged head and adapted to be secured by a screw to the body of theretainer. The said ISO provided by a vertical standard 27 (see Figs. 1,3, 4) and a horizontal bracket 28, forming an attachment of thecast-metal portion of the receiving-hopper C, which is supported on thebase P, as shown in Fig. 3.
